Double Impatiens plant named `Cherry Vanilla`

ABSTRACT

A distinct cultivar of Double Impatiens plant named Cherry Vanilla, characterized by its large red and white bi-color flowers; consistently double and symmetrical flower form; numerous flowers per plant; long peduncles that hold flowers above the foliage; freely branching plant habit; and mounded and spreading plant form.

The present invention relates to a new and distinct cultivar of Double Impatiens plant, botanically known as Impatiens walleriana, and hereinafter referred to by the cultivar name Cherry Vanilla.

The new cultivar is a spontaneous mutation of the seed-propagated Impatiens walleriana Rosette Mixture. The new cultivar was discovered and selected by the inventor in a controlled environment in Palmetto, Fla., as a single plant among a population of plants of Rosette Mixture. This single plant consistently formed red and white bicolor flowers that were fully double.

Asexual reproduction of the new cultivar by terminal cuttings taken at Palmetto, Fla., has shown that the uniqe features of this new Double Impatiens are stable and reproduced true to type in successive generations.

The following traits have been repeatedly observed and are determined to be the unique characteristics of Cherry Vanilla. These characteristics in combination distinguish the new Double Impatiens as a new and distinct cultivar:

1. Large red and white bi-color flowers.

2. Consistently double and symmetrical flower form.

3. Numerous flowers per plant.

4. Long peduncles that hold flowers above the foliage.

5. Freely branching plant habit.

6. Mounded and spreading plant form.

The new Double Impatiens has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light level and daylength, without, however, any variance in genotype.

The accompanying colored photographs illustrate the overall appearance and flower color of the new Double Impatiens, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The first photograph comprises a top perspective view of a typical plant of the new Double Impatiens.

The second photograph comprises a close-up view of the flowers and foliage of the new Double Impatiens.

The following observations, measurements, values, and comparisons describe plants grown in West Chicago, Ill.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
